Description

Multi-monomer seeder for improving soybean ridge close planting yield per unit Technical Field The invention relates to the technical field of sowing, in particular to a multi-monomer sowing machine for improving soybean ridge close planting and unit yield. Background With the increase of global population and the aggravation of cultivated land resource constraint, soybean is used as an important grain and oil crop and protein source, and the large-scale and efficient planting demands of the soybean are increasingly urgent. The large-ridge close planting technology remarkably improves the ventilation and light transmittance, lodging resistance and yield per unit area of the field by enlarging row spacing and optimizing plant spacing configuration, and becomes one of the core means of modern agriculture yield increase. The traditional seeder is provided with 2-3 seeding bodies, the number of seedling belt lines is limited, for example, patent CN202010524909.X describes a seeding device with a 'two-one-single' seedling belt layout, and ventilation and light transmittance are improved by adding a middle single-row seeding body to realize wide-narrow row planting, however, the design still has difficulty in meeting the requirement of ultra-high density planting. Therefore, the multi-monomer seeder for improving the yield of soybean by close planting in a single ridge is provided to solve the problems.
